Except when it's dark and/or windstill. MWh and TWh scale storage is the opposite of inexpensive.
This is exactly what we need to focus on, driving down the costs of storage. Personally i'm a fan of molten salt storage placed at retired coal plant turbines, compressed CO2 seems like a solid bet as well. If flow batteries get their kinks worked out they can be quite cost competitive.
Yes, and :
What are the real costs before subsidies ?
What are the real cost of climate damage we try to mitigate - - which is the basis for subsidies ?

Most interesting indeed.
So the cost of energy is a complex topic and this guy has studied many aspects of that.
Amongst other things he wrote :
Morgan, Tim (2013).Life After Growth. Petersfield, UK: Harriman House. ISBN 9780857193391He discusses the energy cost of energy or : Energy return on investment
He gives an estimate of $130 trillion usd for the global cost of energy transition with a link to the source ... I don't understand how this estimate is made though.
